alternative gearboxes to t-50

[Brenton 86]

I need some clarification on a stronger gearbox, as mine is farked and im not going to rebuild it for it to break again. I have heard vague comments that a supra w5 can be used with a hybrid bell housing. Also if this is true is that series of box easy to find i.e cheap and also how much is the new bell housing. Any help would be greatly appreiciated. Also please only consice responses as i will need to understand exactly what im talking about before i buy the parts. thanks

google is scary isnt it?


yes a W5* + a 4a>W5* bell housing is needed. IIRC the going price for bellhousing is $300-400

w55, w57, w58 are common swaps although the w57 & w58 shifter position is better suited to a ae86

my 57 is from an ra60 celica...cost me $200.

bellhousings can be bought to suit a 4a/w * setup...a few people on these forums sell them otherwise you can contact Dellows to purchase an adaptor plate to suit your t50 housing

search the old toymods forums...theres even stickys that run you through all the different types, cost etc. I can recall numerous threads where all the relevant info was discussed

I got my adaptor plate made for my W55+4A bell housing cost $300 and works fine.

Sometimes the T50 works quite well. It depends on power levels, and the way it is driven.

There are two main ways to fit a W5# gearbox.

Get a bellhousing. There are about 3 different companys making them, from either Aus, NZ or Japan.

Or you can make a 20mm alloy adapter plate. This way you use the T50 bellhousing and the W5# gearbox. The 20mm plate goes inbetween the two. You then need to make other spacers between the crank and pilot bearing. There is a guy in Tas here that has made 2 of these so far. You may also need a custom clutch, and custom tailshaft, and custom gearbox crossmember.

I ran a W series gearbox in my car for a while although it was behind a 3SG but they are strong enough to do the job. I am sure what Jonny has written ubove would be pretty close to accurate, it would be a big job to do it, but I doubt you would have many troubles after that. I though i read on the old toymods forume that Dellows where doing a bellhousing, I think Bill Sherwood had a couple he was selling, maybe all sold now. I have also hear of a guy in sydney that may be having some made up soonish. You can get the right shifter to get it in the standard hole, there are lots of different positions you can get from different models.

Thanks for the help, would someone be able to give me names of these companies and possibly there ph. numbers as im having trouble finding them online and in directories. Also with a 4a-w5* i obviously need to change the clutch and tailshaft but can i use the 4agze-t50 flywheel and also dose the slave cylinder still bolt up normally. Iv also been able to find w55's quite easily and cheap, so how different is the shifting positon? i also have more questions which would probably be best answered by the company making the bellhousing so if someone could get me a number it would be greatly appreiciated.
thanks

dellow sells one. qulaity is iffy but that one has the starter on the drivers side. good for turbo.

castlemaine rod shop has them. good qulaity. starter on the passenger side though.

nite parts out of new zealand does them. possibly the best but also most expensive.

theres a place in malaysia that does them. billsherwood buys them and brings them back when he can, hes a pilot.

we just bought a few off him. wont be here for about 2 months though.

If you want to keep similar ratio's the w55 is probably the closest match in that respect.
